3 people have been criminally charged after a 13-year-old boy was found chained naked to a door in Alabama.

The boy’s mother, Danielle Nicole Martin, 32, his stepfather, Joshua Daniel Martin, 26, and his grandmother, Vickie Seale Higginbotham, 58, were all arrested. Police were notified by an anonymous tip that told them they suspected child abuse.

When police arrived, they found the both naked and chained up to a door, with his ankles padlocked together. Upon further investigation, they discovered that he had been chained for over 18 hours, and that this was a repeated incident.

Both the mother and father have placed the blame of the incident onto Vickie, saying that she was the one that put the chains onto him. The father claimed that he was completely unaware of the situation. None of them are believed to have been under the influence of drugs.
